A three-year study of nearly 4,000 adults ranging from age 19 to 94 found that brain health can improve at any age, challenging the common belief that mental sharpness must decline as we get older. Participants spent just a few minutes a day on brain-training activities, and researchers found measurable gains across multiple aspects of brain health, including thinking clarity, emotional well-being, and sense of purpose.

Forests play a crucial role in promoting health and wellbeing, but not all forests provide the same benefits. A large-scale study demonstrates how specific forest characteristics -- such as canopy density and tree species diversity -- can affect various health outcomes. Read more ›

Scientists have made a breakthrough in eco-friendly batteries that not only store more energy but could also help tackle greenhouse gas emissions. Lithium-CO2 'breathing' batteries release power while capturing carbon dioxide, offering a greener alternative that may one day outperform today's lithium-ion batteries. Read more ›

MIT researchers found a way to measure cell density quickly and accurately -- measuring up to 30,000 cells in a single hour. They also showed density changes could be used to make useful predictions, including whether T cells have become activated to kill tumors or whether tumor cells are susceptible to a specific drug.

The orbital angular momentum of electrons has long been considered a minor physical phenomenon, suppressed in most crystals and largely overlooked. Scientists have now discovered that in certain materials it is not only preserved but can even be actively controlled. This is due to a property of the crystal structure called chirality, which also influences many other processes in nature. The discovery has the potential to lead to a new... Read more ›

Fibroblasts play a central role in maintaining healthy tissue structures, as well as in the development and progression of diseases. For a long time, these specialized connective tissue cells were thought to represent a single, uniform cell type. A recent publication shows that fibroblasts in human tissue actually consist of distinct populations with specialized functions. This heterogeneity is key to developing targeted therapies in regenerative medicine and in the treatment... Read more ›

A study has used advanced genetic and genomic techniques to offer a major step forward in understanding and diagnosing infectious intestinal diseases. The large-scale study analyzed more than 1,000 stool samples from people with diarrheal illness to harness two cutting edge tools. The study used metagenomic (DNA-based) and metatranscriptomic (gene or RNA-based) sequencing. Unlike traditional methods, these techniques do not rely on growing organisms in a lab. Instead, they detect... Read more ›

Experts have demonstrated that multiple sclerosis (MS) can successfully be diagnosed using an MRI scan, meaning patients no longer need to undergo a painful lumbar puncture. Experts found that by using a new MRI scan, they could successfully diagnose MS in 8 minutes. Read more ›

African elephants are the largest land animals on earth and significantly larger than their relatives in Asia, from which they are separated by millions of years of evolution. Nevertheless, Asian elephants have a 20 percent heavier brain, as scientists were able to demonstrate. They also showed that elephant brains triple in weight after birth. These results provide potential explanations for behavioral differences between African and Asian elephants as well as... Read more ›

Using synchrotron X-ray nanotomography with detailed 3D imaging and in-situ mechanical testing, researchers are peering inside shark skeletons at the nanoscale, revealing a microscopic 'sharkitecture' that helps these ancient apex predators withstand extreme physical demands of constant motion. After hundreds of millions of years of evolution, scientists can now finally see how shark cartilage works at the nanoscale -- and learn from them. Read more ›

Several varieties of wild spinach that originated in Central Asia show resistance to a destructive soil-borne pathogen that beleaguers growers of spinach seed in the Pacific Northwest -- a finding that can be used to breed hardier crops. Read more ›

Imagine drawing on something as delicate as a living cell -- without damaging it. Researchers have made this groundbreaking discovery using an unexpected combination of tools: frozen ethanol, electron beams and purple-tinted microbes. By advancing a method called ice lithography, the team was able to etch incredibly small, detailed patterns directly onto fragile biological surfaces. Read more ›

Photovoltaic systems are increasingly being installed not only on roofs but also on open land. This does not always meet with citizens' approval. What is known as agrivoltaics (Agri-PV), however, is viewed more favorably, as researchers have now been able to show. In this case, the solar cells are installed in spaces used for agriculture -- such as on pastures or as a canopy over grapevines. According to a survey... Read more ›

Head and neck cancer researchers are reporting the development and testing of HPV-DeepSeek, a novel liquid biopsy assay. In their new study, HPV-DeepSeek achieved 99% sensitivty and specifity for diagnosing HPV-associated head and neck cancers, outperforming standard of care methods. HPV causes about 70% of oropharyngeal cancers in the U.S., which are increasing in incidence faster than other head and neck cancers. Read more ›
